- 'To all whom it may concern:

and tear to which contractors lights" are subjected. l

Be it known that I, ALnxANnnn, F. Jim- KINS, a subject of the King of Great Britain, residing at Baltimore, -State of Maryland, have invented certain new and useful Improvements in Portable Acetylene Generators and-Torches, of which the following is aspecification;

D a The present invention is a division of m 10 pending-application Serial No. 372,972, filed lay 10, 1907, and it relates to a burner or light attachment for portable acetylene generators adapted for use in building or construction work, various engineering operations, life saving service, cireuses and public celebrations where very powerful and coonomical illuminants are required.

The invention has for its principal objects to provide a burner attachment which is especially designed for generators of the characterreferred to so as to be reliable and efficient in service, readilymanipulated' and adjusted for throwing'the light in any desired direction, and durable and substantial in constructionto efi'ectively stand the wear Another object of the invention is the provision of a novel means for'mounting the burner attachment on the generator so that no special gas tight joints are required, although the attachment can be easily and quickly applied or removed in putting the apparatus in order for use'or in taking it a art for shipment or transportation and a though the burner can be freely turned at "all times for directing the rays of light to difierent points.

An additional object is the employment of a burner extension in the nature of a burner standard supported in a tripod of its own and connected by a hose or flexible conduit with the burner standard of the generator or the outlet thereof so that a light can be provided at a point more or less remote from the generator that supplies the gas, the pur-" pose being to furnish one or more li hts by a single-generating ,unit and provide for a reater portability of the-light or lights independently of the generator.

With these objects in view and others, the invention consists of the various novel features of constructionand arrangement of parts, which will be more fully described hereinafter and pointed out with .particularity in the appended claims.

the accompanying drawings, which I illustrate an embodiment of the invention in to designate corresponding parts'throughout theviews.

Referrin to the drawings, A designates generally t e acetylene generator, the details of which will not be here described as reference can be made to my application hereinbefore mentioned for a more'complete understanding of the generatqrysuflice it 'to say that the gas, which flows as soon as the burner valve is opened and generates automatically as long as the light burns, is de-- livered by an upright outlet pipe 1 that connects with ,the gas generating chamber (not shown) in the tank 2 and rises from the bottom of the latter with its upper open end terminating above the maximum water level of the tank, as clearly shown in Fig. 2. This outlet .pipe, which forms the inner or fixed section of the burner standard, has telescopically fitted t-liereover the outer section 01' burner standard proper, designated by 3. This part 3 is a section of pipe somewhat longer and of larger diameter than the outlet pipe 1 so as to project considerably above the latter and loosely slip vertically on and off the same without requiring any fastenings or gas tight joints, as the water in the tank forms a seal between the telesc'oping portions of the pipes. The

pipe 3 carries at its upper end a swinging" burner 4 which is provided with a tip 5 that delivers the gas for the flame, the supply of gas being opened or cut off by a valve 6 in the standard 3. By mounting thestandard in this manner it vcan be turhed freel about the pipe 1 as an axis for throwing the flame in any direction and by swinging the burner on its pivot in a vertical plane the flame can be directed horizontally and upwardly or downwardly so as to light up any desired area where work is carried on.

lVhen the light is to be used at a point some distance from the generator A, a hose extension 7 may be applied to the upper end of the pipe 1, as shown in Fig. 1, and connected by a coupling 8 with the burner standard 3 which is portably supported in a tripod 9 or equivalent device. The tripod consists oflegs 9' to which are secured guide rings or sleeves 9" disposed one over the other for receiving the burner standard, the latter having a coupling 10 which forms a shoulder that rests upon the upper ring 9" to rotatably support the standard on the tripod.

Instead of connecting the extension hose directly to the pipe 1, the burner standard for the generator may be provided with a coupling 11 for attaclnnent with the hose, as shown in Fig. 2, and in this case one or more burner standards B are connected with the hose at a distance from the generator and its standard. The advantage of this form of the device is that a plurality of more or less widely separated lights may be used to illuminate the same area of work from different points or different areas of the work, all from a common generator, and furthermore the lights are, independently movable to throw the'light rays at any desired partof the work.

The pipe standard or burner attachment of the generator forms aquickly removable coupling between thehose and generator to permit the latter to be easily converted for use with or without the hose attachment, and it also allows the hose to be moved around the generator to different points with perfect freedom while the generator remains in situ, without the hose kinking or breaking at the end nearest the generator, as would be the case if the pipe standard in the tank were not free to turn. In other words, the pipe standard forms a swivel joint be tween the hose and generator.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the. construction and of the method of operation, will be readily appreciated by those skilled in the art to which the invention appertains, and while I have described the principle of operation of the in\'ention, together with the apparatus which 1 now consider to be the best embodiment thereof, I desire to have it understood, that the apparatus is merely illustrative, and that'varii'ms changes may be made, when desired, as are within the scope of the claims.

Having thus described my invention,what I claim is: a

1. The combination of a water-containing tank, a pipe arranged in the tank, a generator supplving gas to the pipe, a burner piperemova ly and rotatably mounted on the first pipe and extending into the tank and held in upright position by the first pipe, and a flexible conduitconnected with the burner pipe.

2. An out-door acetylene 1i hting a paratus comprising a generating evice inc uding an outlet pipe, a burner, means forrotatably and detachably supporting the burner on the device said meanscomprising a straight pipe loosely fitted over and maintained upright by the outlet pipe and receiving gas therefrom. said straight pipe and burner being integrally removable from the device. I

3. An out-door acetylene generating and lighting apparatus comprising a generator tank having an outlet pipe terminating at the top of the tank and surrounded by water, a flexible hose outside the tank, a straight pipe on one end of the hose assembled vertically on and telescoped over the outlet pipe and freely rotatable thereon at all times to form a quickly connected and detachable swivel .jointbetween' the hose and outlet pipe, and a. burner standard attachment on the outer end of the hose and including a stand having a bearing in which the burner standard is rotatably mounted.

4. An out-door acetylene generating and lighting apparatus comprising a generator,
